Video of the Day: World’s Largest Super Soaker

Here’s a big, silly project to kick off your summer weekend. YouTuber and former NASA engineer Mark Rober debuted his 7-foot long water gun on July 11. He’s done this sort of thing before, making a giant Nerf gun, but this is even more powerful, shooting water at 272 miles per hour. The video shows how he put the gun together and how it works – using the same principles as the original Super Soaker. He has also posted plans and a list of the parts he and his friend used, in case you want to try this yourself.
